I've seen this, but never really given it much thought.
For me it is always the first character that is deleted. Once I put the character back in it is never deleted again.

A workaround, certainly: put the text in a Text Frame in the anchored frame that contains the imported graphic. And I'm assuming that by "linked" graphic you mean imported.
I've never seen this happen, but then I primarily use FM7, and haven't used the GText tool for years, because it has so many limitations from a text stewardship standpoint.
Does the character indeed get deleted, with the remaining text collapsing into its space, or is it converted to a space, or just sent to back, hidden behind the graphic?
The mentioned issue has been fixed in FrameMaker 11.
This happened to me in FrameMaker 11 (windows) and our engineer caught it in a PDF I created. I was hoping to find a workaround and will try adding a text frame inside the graphic frame. I use these a lot to add callouts explaining parts of screenshots.
